The influence of stimulus sex and emotional expression on the attentional blink.

Abstract

Past studies have demonstrated that angry faces used as the first target (T1) in an attentional blink paradigm interfere with processing of a second, neutral target (T2). However, despite research that suggests that the sex and emotional expression of a face are confounded, no study has investigated whether the sex of a stimulus might interact with emotional expression to influence the attentional blink. In the current study, both the sex and emotional expression of a T1 stimulus were manipulated to assess participants' ability to report the presences of a subsequent neutral target. Although the findings revealed limited evidence to support an interaction between sex and emotion, both the sex and emotional expression of the T1 stimulus were found to independently affect reporting of T2. These findings suggest that both emotional expression and stimulus sex are important in the temporal allocation of attentional resources to faces.
